  1. Open Provenance Model TutorialSession 7: Open Provenance Model Vocabulary

  2. OPMV • The goal • The rationale • Overview of the vocabulary • Overview of existing type modules • Tools and examples • Future development

  3. Our Goal • Enable “responsible” data publication, in order to trace the responsible agents and to reproduce results • Enable to describe provenance of any types of data • Easy to use and extend • By people who publish Linked Data • By developers of Linked Data publishing tools

  4. Immutable piece of state, which may have a physical embodiment in a physical object, or a digital representation in a computer system. ARTIFACT

  5. The Rationale • Grounded upon existing SW technologies • Do not explicitly define a graph, OPMGraph • Named Graphs • Reuse existing vocabularies • Lightweight • 3 classes and 12 properties • Reuse 3 classes from the W3C Time Ontology

  6. Overview of the Vocabulary • Defined as a vocabulary expressed using OWL • Implement the core concepts of the Open Provenance Model • No specific granularity prescribed • Partitioned into: • The Core Module • Other typed modules: common, xml, gate, sparql

  7. OWL Ontology for OPM

  8. Overview of the OPMV Vocabulary 1 prefix time: http://www.w3.org/2006/time# Agent Object properties implementing OPM Object properties not as exactly defined in OPM rdfs:subClassOf relationships Artifact wasControlledBy owl:Thing wasGeneratedBy used Process wasTriggeredBy wasGeneratedAt time: Instant time:TemporalEntity time: Interval

  9. OWL Ontology for OPM (1) pc1:p5 a opm:Process ; opm:account pc1:black ; opm:label "Reslice 1" . pc1:an1_p5 a opm:Annotation . pc1:pr_18 a opm:Property ; opm:uri "http://openprovenance.org/primitives#primitive" ; opm:value "http://openprovenance.org/primitives#reslice" . pc1:an1_p5 opm:property pc1:pr_18 . pc1:p5 opm:annotation pc1:an1_p5 . pc1:u_103 a opm:Used ; opm:effect pc1:p1 ; opm:role pc1:r_102 ; opm:cause pc1:a3 ; opm:account pc1:black . pc1:gr_273 a opm:OPMGraph ; opm:hasAccount pc1:black ; opm:hasProcess pc1:p5 , ...; opm:hasArtifact pc1:a25p, ...; opm:hasDependency pc1:u_103, ...

  10. Example: OPMV pc1:p5 rdf:type opmv:Process ; rdfs:label "Reslice 1" . pc1:a3 rdf:type opmv:Artifact opmv:wasGeneratedBy [ rdf:type opmv:Process; opmv:used pc1:p1 ] . pc1:p1 rdf:type opmv:Artifact .

  11. Example: OPMV + Named Graphs pc1:gr_273 { pc1:p5 rdf:type opmv:Process ; rdfs:label "Reslice 1" . pc1:a3 rdf:type opmv:Artifact opmv:wasGeneratedBy [ rdf:type opmv:Process; opmv:used pc1:p1 ] . pc1:p1 rdf:type opmv:Artifact . } pcl:gr_273 rdf:type <http://www.w3.org/2004/03/trix/rdfg-1/Graph> .

  12. Comparison with OPM OWL • A more intuitive OWL ontology and RDF representation • Take full advantage of SW technologies • Lack of explicit semantics for graph membership • Not too much for reasoning • (Probably) a less complete implementation of the OPM Specification

  18. Publishing OPMV Provenance • ProvenanceJS (Hands-on session)

  19. Future Development • More typed modules • A guide on how to publish provenance • Where and how much • What is the minimum provenance • How to represent the information
